A Dual-Branch Deep Learning Framework for Macroscopic Area and Microscopic Contour Prediction of EMU Wheelset Wear

Accurately predicting the nonlinear degradation trajectories of electric multiple-unit (EMU) wheelset treads is crucial for ensuring dynamic safety and optimizing predictive maintenance. However, existing data-driven methods struggle to simultaneously quantify macroscopic material loss and reconstruct microscopic worn...

Multi-Axle Reference and Temporal-Consistency Deep SVDD for EMU Traction Motor Bearing Anomaly Detection Using Field Vibration Data

Field vibration monitoring of EMU traction motor bearings is commonly constrained by weak or relative labels, fluctuations in operating conditions, and limited abnormal samples. Under these conditions, learning a normal boundary from a single bearing position may be unstable, and isolated score spikes may lead to unrel...
